PHOTOGRAPHIC-PRINTIN G FRAME.

Specication of Letters Patent. l Patented Mar. 10, 1914.

Application led November 3, 1913. Serial No. 798,932.

To all 'whom 'it may concern -Be itknown that I, HARVEY G. WOLF, a citizen of the United States, and a resident of the city of Covington, county of Kenton, and State of Kentucky, have linvented certain new and useful Improvements in Photographic-Printing Frames, of which thel following is a specification.

My invention relates to printing frames and more especially to such devices adapted for photographer-suse l Y The object of my improvement is to provide a simple andelfective printing frame composed of two co-extensive frames hinged together and provided with a spring lock adapted to lock the frames together.

A further object isto provide a frame as.

mentioned having elongated plates arranged between the frames and adapted to be moved towardand away from each other to dene -the limits of a picture to be printed.'

Other objects will appear hereinafter: `The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention-will behest` understood by 'reference' to the accompanying drawing forming a part of this specification, and in Figure lis .a view, in perspective, of a printing frame embodying my l invention, and Fig. 2 isV a section of the same taken on .extending entirely around the outer. edge of Y' said frame and parallel withthe sides theref of. Disposed transversely across the frame V3 are elongated plates 8, each of which has its ends bennes at 9, and its-end portion engaging 1n the groove 7 in the longitudinal` edges'of the frame 3. The elongated plates 8 are adapted to be moved toward and away from: each other as willbe readily understood.l Disposed longitudinally of the frame 3 are plates 10 having their vends bent as at 11 and their rend portions engaging the portion of VsaidV oove in the end-edge of the frame 3. Said plates 10 Vare-adapted t0 be ymoved toward and away from eachother" plates 8 and 10' in desired positions. The

facing 12 further prevents any light from entering under plates 8 and 10 to the edges of a printing paper held undersaid plates.

On the under side of frame l4is an elastic facing 13 similar to facing v12 and provided to prevent light from entering between the frames 3 and 4 when locked together. In the under side of plate 4 is fitted a negative 14 having the desired negative picture thereon. The negative 14 of course is to be changed in printing different pictures the same as is the usual custom. y

In the frame 3 is mounted a backing board 15 having springs 16, one of which is shown, to hold it in position ressing a sheet of printing paper againste ongated plates 8 and 10. The backing board 15 .and its means for .maintaining 1t in frame 3 are of ordinary construction and need no further descriptionv here.

In use, the backing board 15 is removed from :trame 3 anda printing paper laid, with its sensitive side 'against `elongated plates 8 and 10, the latter being brought suiiic'iently close to each other to produce the desired size or bounds of the picture. The backing board 15 is then placed on the sensitive paper and locked in frame 3- the same as is the usual custom. A negative 14 is then placed in position in the opening of facing 13 in frame 4 and the frames v3 and 4 moved on their hinge 5 vuntil the spring catch 6 locks the same securely together. The frame is then exposed to light in the usual manner. Where negatives are i on films a clear glass plate is used in the position indicated by the member 14 in Fig. 1 and the film-negative placed on the member 14 and the frames 3 and 4 locked together with the iilm contacting the sensitive paper under plates 8 and 10 as is the usual custom. f

While I have illustrated and described the preferred form of construction for carrymg my invention into eiect, this is capable n of variation and modification without departing from the spirit of the invention. I,

therefore, do not wish to be limited to theA precise 'details of construction set forth, but

desire to avail myself of such variations and sponding ends of said frame; a spring catch modications as vcome within the scope of locking the other corresponding ends of said the appended claims. frames together; two parallel elongated Having described my invention what I plates arranged longitudinally of and be- 6 claim as new and desire to secure by Letters tween saidframes, having their endsin4 said 40 Patent is: grooves and adapted to be moved toward l.
